I created folders. It is an option in the Bookmarks feature. When I bookmark threads, I get a drop down menu of my folders and can place the thread into the appropriate folder. I have Poetry, Grammar, Spelling, Vocabulary, Lit Responses, Novel Titles, etc. When I go to My Desk, my folders appear in a sidebar and when I open a folder, there are all the bookmarked threads in that category.

You can also place entire threads or single posts into Collections or into a Scrapbook ny clicking on the scissors icon on the top right corner of any post. You first have to set up your collections by topic. I use the same topics I have on my flash drive (subjects or curriculum areas.)

MIddling, I've never thought about using the folders for bookmarks. I use the folders to sort all the PMs I get with ideas or requests for info or collaboration with people that I PM with regularly.
